With the success of its first location in Tokyo, Mars opened this branch in West Hollywood to provide the same exquisite nail service. Though you can get just a regular mani/pedi, the raison d’être is the inventive Japanese nail art, set with gel so as not to damage your own nails. Each private room comes complete with a flat-screen TV, large leather chair, and headphones. With prices to match. Waxing services are also available.
